FLOAT-VALVE.

Specification of Letters Patent.

Patented May 28,1912.

Application fi1ed May 31, 1911. Serial No. 630,291.

To all whom/2'1, may concern:

Be it known that we, ELI A. BLILER and CHRISTOPHER C. BLILER, citizens of the United States, residing at Livingston, in the county of Park and State of Montana, have invented new and useful Improvements in Float-Valves, of which the following is a specification.

The invention relates to valves, and more particularly to the class of float valves for use in connection with flush tanks.

The primary object of the invention is the provision of a valve of this character in which the water supply to a flush tank will be controlled, so as to prevent the overflow thereof on the filling of the same with water.

Another object of the invention is the provision of a valve of this character in which the float arm is formed of hinged sections, which latter are locked against independent swinging movement by means of a collar, and one of the sections carries thereon a balancing weight, so as to regulate the float carried thereby.

A further object of the invention is the provision of a valve of this character which is simple in construction, thoroughly reliable and efiicient in operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a fragmentary vertical sectional view through a flush tank, showing the valve constructed in accordance with the invention mounted therein. Fig. 2 is a vertical sectional view of the float valve, with the valve in closed position. Fig. 3 is a similar view, showing the valve in open position. Fig. 4 is a plan view, the locking collar carried by the sections of the float arm being broken away. Fig. 5 is a fragmentary vertical sectional view through the valve and the air tube.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the valve comprises a cylindrical casing 10 having the lower end terminating in a threaded tubular shank 11 for connection with a water supply pipe 12, the said shank being adapted to pass through the bottom 13 of a flush tank 14. The casing 10 is provided with an outlet pipe 15 connected with the side thereof, so that the water from the inlet pipe may pass into the casing and thence through the outlet pipe into the flush tank, the supply of water being controlled by means of valve mechanism, presently de' scribed.

Threaded or otherwise secured in the top of the casing, eccentrically thereof, is a vertical tubular upright 16, the upper end of which is closed, while its inner end communicates with the interior of said casing and forms an air chamber operating to prevent pounding and trembling of the valve, when the fiow of water is suddenly stopped.

Surrounding the tubular upright 16 is a collar 17, the latter carrying a binding screw 18 which engages the said upright 16 for locking the collar in adjusted position, the binding screw 18 being also designed to serve as a pivotal connection for the inner end of a float arm, comprising rod sections 19 and 20, respectively, the outer end of the rod section 19 being threaded for receiving a sleeve 21 which is carried thereby, the sleeve being formed with spaced parallel limbs 22, between which is engaged the adjacent end of the outer rod section 20, which latter is hinged between the limbs 22 by means of a cotter pin 23 connecting the same. Threaded upon the bifurcated end of the sleeve 21 is a locking collar 24 which is adapted to sustain the rod sections, against independent swinging movement, but upon the working of the collar 24 upon the sleeve, the outer rod section 20 may be swung upwardly or downwardly at right angles to the inner rod section 19, as will be clearly obvious. Fixed to the outer end of the outer rod section 20 is a hollow spherical float body 25 which is of the ordinary well-kn0wn construction.

Formed centrally in the casing 10 is a vertical bore 26, the latter opening through a concaved valve seat 27 at its inner end, the said valve seat being concentric to the vertical bore 26 and spaced from the free end of the shank 11, while the outer end of the bore opens through the top of the said casing. At right angles to the bore 26 and formed in the casing 10 is a lateral passage 28, the same intersecting the said bore and opening through one side of the casing 10 for communicating with the outlet pipe 15.

WVorking within the bore 26 is a valve stem 29, the upper end of which is bifurcated to form spaced ears 30, between which is received the inner flattened portion 31 of the inner section of the float arm, which latter is connected with the cars by means of a pivot 32, so that upon the raising or lowering of the float arm, the valve stem 29 will be raised and lowered within the bore 26 in the valve casing. The lower end of the valve stem 29 is formed with a reduced extension 33 of considerably less diameter than the bore 26, and carries a resilient valve 34, which is adapted to contact with the valve seat 27 on the lifting of the valve stem 29, so as to close the bore 26, thereby shutting off the supply of water from the water supply pipe 12 through the valve casing 10 to the flush tank, but upon the lowering of the valve stem 29, the said valve 34 will drop from the seat 27, thereby opening the bore 26 for admitting water from the water supply pipe 12 to the flush tank, the upper portion of the valve stem 29 being of a corresponding diameter with respect to the bore 26, and when in lowered position only partially intersects the passage 28. Thus, in this manner, the same will not become closed when the valve is away from the seat 27 in the valve casing.

Adjustably threaded on the inner rod section 19 of the float arm is a balancing weight 35, which, when regulated, will enable the proper seating of the valve 34, when the float arm is being raised within the flush tank.

In the operation of the valve, when the flush tank is full of water, the float body 25 will be in its uppermost position, as will be readily understood, and thus it will be seen that the valve 34 will be closed, or in other words, in contact with its seat 27 to prevent any more water entering the flush tank from the water supply pipe 12- As the water is drained from the flush tank, the float body 25 moves downwardly with the water, thus moving the valve stem 29 downwardly and opening the valve 34 relative to its seat 27, so that water will be admitted into the valve casing from the water supply pipe 12, and be caused to flow through the bore 26 and passage 28 into the flush tank for the refilling of the same, and consequently mov- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

ing the float upwardly therein, so that when the water in the flush tank has reached a predetermined height, the valve 34 will be again seated, thereby shutting ofi the supply from the water supply pipe 12 to the said tank.

Formed within the casing 10 is an air passage 36 which opens into the upright 16 and into the shank 11 and spaced a distance beyond the valve seat 27 in said casing.

What is claimed is:

1. A valve of the class described, comprising a casing adapted to be mounted in a flush tank and connected with the water supply, said casing being provided with a central bore of two different dimensions to provide a valve seat interiorly of the casing, a valve rod slidable in the smaller dimension in the bore and having a valve for engagement with the seat, a closed hollow tube rising from the casing and forming an air chamber and having direct communication with the bore in the larger dimension thereof, the said casing being further provided with an outlet opening through one side thereof and intersecting the smaller dimension in the bore, a collar slidable upon said hollow tube, a float arm, a pivot connecting the float arm to said collar and also looking the latter upon the tube, a pin connecting the valve rod with. the float arm, a float having a break joint connection with said float arm, and a lock ing collar surrounding the said break joint and adapted to move onto and off of the same for unlocking and locking it.

2. A float valve comprising a valve casing communicating with a liquid supply and having an inlet and an outlet, a closed hol low tube rising from the casing and forming an air chamber communicating with the interior of the casing, a member mounted upon the tube, a float arm, and a pivot connecting the float arm to said member and also looking the latter upon the tube.

In testimony whereof we affix our signatures in presence of two witnesses.
